Works inside Gmail and Outlook on the web.

How it works

ForthWrite captures your tone, sentence rhythm, and sign-offs from your actual sent emails, then uses that profile to generate drafts that match how you write, not a generic AI voice. Every draft you edit or send improves the model over time.

  • Auto-draft: replies waiting in Gmail before you open your inbox
  • Voice matching from your real sent mail, not templates
  • Recipient-aware drafts that adapt to who you are emailing
  • Prompt Lab for version-controlling and A/B testing your persona prompt
  • BYOK support: bring your own API key for Claude, OpenAI, Grok, Mistral, and more
  • Works in Gmail and Outlook on the web, plus a standalone browser widget

Who uses it

Professionals who send high volumes of relationship-critical email: lawyers, financial advisors, recruiters, account executives, founders, and anyone who wants their inbox handled without sounding like a chatbot wrote it.

bestprover features and specs

  • Specialized Focus
    BestProver appears to be designed around a specific niche (theorem proving or problem verification), which may make it more effective for that particular use case compared to general-purpose tools.

Analysis of bestprover

Overall verdict

  • I don't have verified, up-to-date information about 'bestprover' (en.bestprover.com) to confirm its legitimacy, quality, or reputation, so I can't give it a reliable endorsement. Before using it, you should independently verify the company through trusted review sources and official records.

Why this product is good

  • I have no confirmed data on this specific website's business practices, reviews, or track record.
  • Unfamiliar or low-profile domains can carry higher risk of being scams, low-quality services, or lacking proper business registration.
  • Legitimate assessment requires checking third-party reviews (Trustpilot, BBB, Reddit), WHOIS domain history, SSL certificate details, and business registration.
  • Claims made on the site itself cannot be taken as verified proof of quality or trustworthiness.

Recommended for

  • Users who first do their own due diligence, such as checking independent reviews and verifying business legitimacy before engaging.
  • Not recommended for anyone seeking a service without first confirming its credibility through trusted third-party sources.
  • Those willing to start with small, low-risk transactions to test service quality and reliability before committing further.

Questions & Answers

As answered by people managing bestprover and ForthWrite.

What makes your product unique?

bestprover's answer

Bestprover is unique because it aggregates reviews from multiple qualified sources into a single, streamlined rating, solving the issue of fragmented information across platforms. Unlike competitors, bestprover uses an AI-powered algorithm that enhances the discovery of top-rated businesses and services tailored to each userโ€™s needs. Additionally, it provides businesses a direct line of engagement with potential customers within a sleek, user-friendly interface that works seamlessly across multiple devices.

ForthWrite's answer:

ForthWrite learns your writing style from your actual sent mail, not a generic prompt. Every draft sounds like you wrote it because it was trained on how you actually write. It also auto-drafts replies before you open your inbox, so your email is partially handled before your day starts.

Why should a person choose your product over its competitors?

bestprover's answer

Bestprover simplifies the process of finding reliable information by consolidating reviews into one easy-to-understand score, eliminating the need to check multiple sites. With its AI-driven recommendations, users get personalized insights, saving time and ensuring a better decision-making experience. For businesses, it offers a unique engagement channel, providing direct visibility to customers in a space optimized for user experience and trustworthiness.

ForthWrite's answer:

Most AI email tools give you a blank box and a "write for me" button. ForthWrite builds a voice profile from your sent history and gets more accurate with every draft you edit or send. Unlike ChatGPT or Gemini, it works natively inside Gmail and Outlook with no copy-paste. Unlike Lavender, it writes the draft, not just scores it.

How would you describe the primary audience of your product?

bestprover's answer

Our primary audience includes two main groups:

Consumers โ€“ individuals looking for reliable, aggregated reviews to quickly find and trust the best-rated companies and services across various sectors. They appreciate convenience, transparency, and the efficiency of having all reviews in one place. Businesses โ€“ companies aiming to expand their reach by directly engaging with new customers and showcasing their reputation in an environment where ratings are centralized and credible.

ForthWrite's answer:

Professionals who send high volumes of relationship-critical email and cannot afford to sound generic: lawyers, financial advisors, recruiters, account executives, consultants, and founders managing their own inbox.

What's the story behind your product?

bestprover's answer

Bestprover was created out of a shared frustration with the current review landscape, where users spend excessive time jumping between platforms and still often get an incomplete view. The team envisioned a platform that centralizes reviews in one place, offering transparency and ease for both users and businesses. With bestprover, they aimed to create a more efficient and accurate way for consumers to make decisions while giving businesses an authentic connection with their audience.

ForthWrite's answer:

Built out of frustration with AI writing tools that produce text that sounds nothing like the person sending it, and as a way to handle large amounts of daily email. The core insight was that your sent mail is the best training data you already have, and no tool was using it.

Which are the primary technologies used for building your product?

bestprover's answer

Bestprover is built using a Next.js frontend and a Python Django backend. These technologies provide a robust foundation for handling large-scale data aggregation, a high-performance UI/UX experience, and seamless compatibility across devices. The AI algorithm is integrated to analyze, rank, and recommend top-rated businesses based on review data.

ForthWrite's answer:

Next.js, React, Supabase, Anthropic Claude, OpenAI, Stripe, Vercel, Chrome Extensions API

Who are some of the biggest customers of your product?

bestprover's answer

While bestprover is still growing, its early adopters include a range of small to mid-sized businesses that understand the value of having a consolidated review platform to connect with potential customers. As bestprover continues to expand, it aims to onboard larger companies and chains that prioritize customer engagement and reputation management.

    I built ForthWrite to fix generic AI email, and I still use it every day

    I built ForthWrite because I kept sending emails that sounded like they came from the same generic AI as everyone else. After launching it, I still use it for my own inbox every day, which is about the most honest endorsement I can give.

    The Chrome extension lives inside Gmail and Outlook on the web. Open a thread, hit Alt+Shift+D, and a draft comes back in your voice, not a template. The free tier is real: 10 drafts per week, no API key, no credit card. Voice matching is included on free, because that is the point.

    What keeps it useful compared to Gemini or a chat tab: it learns from what you actually send. Every edit you make before hitting send becomes a signal. Over time the drafts drift closer to how you really write, and the dashboard shows the improvement curve so you can see it happening.

    The web compose surface lets you draft from forthwrite.ai without installing anything, useful for people who want to try before committing to the extension.

    Standard adds recipient-aware and intent-aware drafting plus AI coaching. Pro adds auto-draft (replies waiting when you open Gmail), batch replies, and Prompt Lab for version-controlling your prompts. Teams adds a shared persona and seat-level analytics.

    ForthWrite is not for everyone. If you just need quick replies and tone does not matter, Gemini is free and already in your inbox. ForthWrite is for people where tone does matter: client communication, relationship-driven threads, external correspondence where sounding off costs something real.

    Disclosure: I am the founder and use it daily. Happy to answer questions in the comments.

    ๐Ÿ Competitors: Jace.ai, Fyxer, Mailmeteor
    ๐Ÿ‘ Pros:    Drafts land inside gmail and outlook; no copy-pasting from a chat window|Voice matching is on the free tier, not paywalled behind paid plans|No api key, no credit card to start; free tier runs on a server-side proxy|Learns from every edit you make before sending; drafts improve over time|Full keyboard flow: alt+shift+d to draft in any thread, no mouse required|Byok on paid plans, 9 providers supported, keys encrypted at rest|Web compose at forthwrite.ai works without installing the extension at all
    ๐Ÿ‘Ž Cons:    10 free drafts/week is enough to evaluate, not enough for a heavy inbox|Auto-draft, batch replies, and prompt lab all require the pro tier|Early-stage product; fewer third-party integrations than mature inbox tools|No mobile app: the extension and add-in are desktop-only (chrome on web, or the outlook desktop add-in)
